The French website jeuxvideo.com just uploaded a 15 min video of the lost shores here :http://www.jeuxvideo...us-00108286.htm
Everything is in French but you can turn the sound off and just watch it.
There are spoilers : the video even shows how the final boss looks ( it's amazing ), so be aware of that.

The tester enjoyed the dungeon a lot.
He liked the island too but said that it was mostly populated by one type of mobs and it could get a little bit boring

Man , that ranger spammed No. 1 skill all the time , horrible. The karka is awesome, i love that roll :-)). Level 1 difficulty looks easy enough to get the point of the dungeon.

Well shortbow rangers spam 1, warriors use greatswords, mesmers summon clones and eles are fun to play. Nothing really worth noting unless you also like talking about the wetness of water.

Actually, the dungeon looks way too easy at level one. The new dungeon should at least be comparable to the current dungeon at level 1. We only saw very short snippets, but mobs that aren't even veteran and lone veterans is on the level of easily soloable. Literally, that's the stuff you find in the open world. Why have boring, easy levels that people will plow through? Even the supposedly easily pugged story mode dungeons use silver instead of veteran mobs. Really hope we won't have to do 30 runs before we start seeing groups of nothing but silver and champion foes.
